Abstract

The invention discloses a method and system for maintaining continuity when switching from WLAN to WLAN or 3G, including: a gateway device judges the cause of de-association according to the received de-association message sent by the first port of the access point; Receive a connection request message sent by the WLAN terminal before the timing ends; when the connection request message is an association request message between the WLAN terminal and the second port of the access point, the gateway device carries the PDP context The PDP IP address used in the last association of the WLAN terminal is allocated to the WLAN terminal for network switching; when the connection request message is the PDP context activation request message in the 3G service establishment request, the gateway device feeds back a PDP context activation response message to perform network switching. The invention does not need to add new network elements, realizes the continuity of services when switching between networks, and saves equipment upgrade costs.

Description

technical field [0001] The invention relates to the technical field of wireless network switching, in particular to a method and system for maintaining continuity when switching from WLAN to WLAN or 3G. Background technique [0002] The home gateway (HGW) is the hub for the connection and intercommunication between the home network and the telecom operator's network. It provides networking means for each terminal in the home network, and is responsible for the intercommunication and remote control between the public network and each subnet of the network (PC, telephone, home appliance, lighting, etc.), and it is also the way for users to obtain various value-added from the telecommunications network and the Internet. service channel. [0003] With the popularity of smart terminals, traditional 3G networks are facing unprecedented challenges. As a flexible broadband wireless IP access method, WLAN technology has been clearly recognized by the industry due to its high access...
